Fracture of the vertebral end plate in the lumbar spine has been reported as a rare lesion occurring in the adolescent period. It is characterized by variable degrees of sign and symtom related to the degree of block on myelogram and the level of end plate fracture. Trauma or strenuous sport activity seems to play an improtant role in the production of fracture of vertebral body in the adolescent period. We experienced three cases of fracture of lower lumbar vertebral end plate in teenaged patients, two males and one female. Two patients showed upper end plate fracture with severe neurologic deficit on the involved root level and a strong positive on straight leg raising test, and one patient showed lower end plate fracture with slight neurologic deficit. Two patients with upper end plate fracture were treated with partial laminectomy with removal of fracture fragment and one patient with lower end plate fracture was treated with bilateral laminectomy and posterolateral fusion. The method of treatment will depend upon the type of fracture and the degree of neurologic symptoms. We obtained satisfactory results with posterior decompressive laminectomy and removal of fracture fragment with or without fusion.

Assays for HBsAg, HBV DNA, anti-HBc and anti-HBs of 285 units of packed red blood cells supplied by Taegu Red Cross Blood Center were performed to evaluate the correlation between the prevalence of HBV DNA and the serologic markers for hepatitis B virus. None of 285 plasma samples was positive for HBsAg, however, HBV DNA were detected by polymerase chain reaction in 2 samples which both presented only with anti-HBc positivity.. Of 204 samples tested for anti-HBs, 96 samples(47.1%) were positive and among 216 samples tested for anti-HBc, 80 samples(37.0%) were positive. Of 193 samples tested for both anti-HBs and anti-HBc, 80(41.1%) were all negative and 48(24.9%) were positive on both tests. Those samples which showed positivity only to anti-HBc were 25(13.0%). Considering the above results, transfusion-transmitted hepatitis B virus infection could be prevented by discarding anti-HBc positive blood, however, that may bring insufficient supply of donor bloods in the country like Korea where the prevalence of anti-HBc is high. Anti-HBc positive blood unequivocally positive for anti-HBs should be considered noninfectious for HBV and should be allowed to be transfused. It would reduce the amount of discarding donor blood as the routine blood donor screening tests presently used at Korea Red Cross Blood Center supplemented by anti-HBs and anti-HBc testing.

BACKGROUND: Induction of general anesthesia with tracheal intubation and skin incision are potent stimuli that can induce increased sympathetic activity, heart rate and blood pressure. We compared the hemodynamic response and catecholamine concentration during general anesthesia with intravenous clonidine pretreatment, a centrally acting -2 adrenoceptor agonist, and without pretreatment. METHODS: Forty ASA I or II patients aged from 20 to 60 years undergoing elective surgery were randomly allocated to two groups. In group I, 5 ml of 0.9% normal saline as control administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O (2.5L/min)-O2 (2.5L/min)-enflurane (1.3~1.8 vol%). In group II, 4 g/kg clonidine diluted in 5ml of normal saline administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O-O2-enflurane (0.5~1.0vol%) and 2 g/kg/hr clonidine was continuously infused. We measured blood pressure, heart rate and plasma catecholamine at preinduction, 1 minute after intubation (T1), 1 (T2) and 30 minutes after skin incision (T3) and compared with group I. RESULTS: There was statistical significance in systolic and diastolic pressure at T1 between two groups. There was statistical significance in heart rate, epinephrine and norepinephrine at T1, T2 and T3 between two groups. CONCLUSION: The elevation of blood pressure, heart rate and plasma catecholamine accompanying tracheal intubation and skin incision may be prevented by administration of intravenous clonidine.

We had precise and accurate information concerning the position of the foreign body, its nature, and the extent of damage to the eye. A linear half-thickness incision which was paralleI to the limbus was made on the sclera immediately external to the location of the foreign body. A lamellar scleral undermining was performed on the both sides of a single scleral incision. Diathermy was applied in the area undermined. A T-shaped incision went all the way through the lamellar scleral bed, cleanly eXIo3ing the dark uveal tissue. The hand magnet was brought on the exposed choroid; the bulging of the choroid was obvious proof of its presence. And then gentle to-and-fro scratching with a nonmagnetic spatula on the bulging uveal tissue caused the foreign body to be extracted easily. The T-shaped incised scleral bed was closed. The preserved human sclera was burried in the lamellar dissected sclera. Practically any portion of the sclera up to a few millimeters in front of the optic nerve head can be approached. There were significant advantages to these procedures such as a high successful rate, a sufficiently promising effect in prophylaxis and treatment of the retinal detachment. Among 15 cases of the magnetic lOPB. including 7 cases of combined retinal detachments. 14 cases of IOFB and all cases of the retinal detachment showed to be completely recovered. The procedure failed in 1 case, in which foreign body located and adhered firmly on disc.

This report summarizes the authors' experiences in 119 dialysis on 12 patients of chronic renal failure treated at Sacred Heart Hospital from Jan. 1, 1973 through May 14, 1974 using Kill type artificial kidney. The average effect of 119 hemodialysis in correcting abnormal blood levels of B.U.N., creatinine, potassium and changes of body weight are as follows; Blood urea nitrogen 115.2mg% -> 70.6mg%, Serum creatinine 9.7 mg% -> 7.5mg% Serum potassium 5.2 mEq/L -> 3.8mEq/L, Body weight 55.1kg -> 52.9kg
